ALBANY — More victims of misdiagnosed cancer are about to get their day in court.

The Legislature on Wednesday passed a scaled-back version of Lavern’s Law that would start the window to bring medical malpractice cases involving cancer when an error is discovered by the patient, not when the mistake occurred, as under current law.

But one family who won’t benefit from the change is that of the woman for whom the law is named — Lavern Wilkinson.

Wilkinson was a 41-year-old Brooklyn mom who died in 2013 of a curable form of lung cancer after doctors at Kings County Hospital misdiagnosed her. By the time she sued, the window to file had expired. She left behind a 15-year-old autistic and developmentally disabled child, Micalia Squires, who needs round-the-clock care.

Unlike a previous version of the legislation, the bill passed by the Senate and Assembly Wednesday, on what was scheduled to be the last day of the legislative session, does not contain a one-year window to revive cases that are time-barred under current law.

“I’m disappointed and I’m very upset about it,” said Wilkinson’s aunt, Gloria O’Connor. “That’s not nice.”

O’Connor says she takes some solace that other families, moving forward, won’t have to go through what Lavern’s family did, and she urged Gov. Cuomo to sign it into law.

The revised bill says a misdiagnosed cancer victim would have 2 1/2 years from the date of discovery to bring a lawsuit.

The original Lavern’s Law bill would have also covered all medical malpractice cases. But the Senate GOP wouldn’t bring it to the floor.

“You have to get a consensus, and to get a consensus sometimes you have to modify things,” said Senate bill sponsor John DeFrancisco (R-Syracuse).

But DeFrancisco, who was a long-time trial lawyer, said the bulk of the cases occurred where a cancerous mass was found, but not disclosed, and the statute of limitation ran out before a patient could bring a lawsuit.

Under the revised bill, a cancer victim who was misdiagnosed would have 21/2 years from the date of discovery to bring a lawsuit. But if the negligence happened more than seven years prior, the person would be barred from suing.

Assembly bill sponsor Helene Weinstein (D-Brooklyn) said that while she would have preferred to do the broader bill that encompassed all victims of medical malpractice, the more limited version is a “good first step.”

The bill’s namesake, Laverne Wilkinson, died in 2013 of curable lung cancer.

The Daily News has advocated for passage of the law the past several years. The Assembly passed a version of the bill two years ago. The Senate never had, until Wednesday.

Gov. Cuomo previously said he’d sign the original Lavern’s Law if it passed the Legislature. A spokesman said the governor will review the revised bill.

Lavern’s Law has been strongly opposed by the deep-pocketed medical establishment, which has argued that many of the states that have similar measures in place also have caps on pain and suffering awards and limits on total damages.

The state Medical Society said Wednesday it is “extremely concerned about the ultimate impact to New Yorkers’ access to care” if the new bill is signed into law.

Tom Stebbins, of the Lawsuit Reform Alliance of New York, groused that “at the behest of the trial lawyers, lawmakers in Albany have laid the groundwork to turn New York’s medical care crisis into a full-blown catastrophe.”
